What is the factored form of the polynomial z² − 10z + 25?

Answers

Answer:

( z - 5 ) ( z - 5 )

Add any three numbers of the following and answer should be 60?(2 , 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58)

Answers

Answer:

This is not possible.

Step-by-step explanation:

The given series is : 2 , 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58

Now, adding any three numbers to get 60, is not possible.

The numbers are in the form 2+4n where n is a positive integer.

Summing together three such numbers you get 6+4N

(N = n1 + n2 + n3, ...)

We want to get 6+4N= 60

=> 4N =54

=> n1+n2+n3 =27.5

Hence, it is not possible.
